If you
do this, you would need to specify individual column widths. Otherwise, the
browser will generate each table with column widths to match the
data.
I'm
more of a fan of generating the first 20 items that you wish to display, saving
keys in your session to know where you left off, and generating pages with
"Next" and "Prev" buttons.
how about break one big table to several small
tables with the same amount of collums? You can hide the outer border so
the user will think that is one table.

I need some
help. I have a servlet that generates about 150
items and creates an HTML table. It takes about 45 - 60 seconds to run.
First, I would like to create pages with 20 - 30 items per page. I
through of a way to do this with _javascript_ and DIV tags but we know why
that isn't the best solution for multi-browser support and doesn't help
with the issue below.
Second, I would like to provide the illusion
of speed where as soon as the servlet is done with the first 20 results,
throw up the HTML and let the process keep going with the other 130 while
the users looks at the first 20.
I don't think you can do
that. See, the HTML engine in your browser will only start rendering
the table on the screen unless it encounters the </table> tag. I
could be wrong but I really don't think there is a way to start displaying a
table without having all the table elements and a closing tag. I would
recommend either getting all the elements for the table in advance in a
different thread while the user is busy doing something else if this is
possible. Then when the user requests the table all you have to do is
just construct your table with the elements that you have already
prefetched.
